I owe my success to the fact that I never had a clock in my workroom.

Success depends upon previous preparation, and without such preparation, there is sure to be failure.

I don't believe in leaving things to luck. I believe in hard work and preparation.

Success is 90% perspiration and 10% inspiration!

I've come to believe that each of us has a personal calling that's as unique as a fingerprint-and that the best way to succeed is to discover what you love and then find a way to offer it to others in the form of service, working hard, and also allowing the energy of the universe to lead you.

We all know you don't get successful just by having a good idea or working hard. You get successful by being lucky too. If I had to support my family growing up, instead of having the time to learn how to code. If I didn't know that I was gonna be fine if Facebook didn't work out, then I wouldn't be standing up here today. And if we're honest, we all know how much luck we've had.
